You need to compile your kernel and make sure you set a few options...modules are kernel specific
Loadable module support -> Enable loadable module support: ENABLED
Loadable module support -> Module unloading: ENABLED
Loadable module support -> ENABLED
Processor type and features -> MTRR (Memory Type Range Register) support: ENABLED
Device drivers -> Character Devices -> /dev/agpgart (AGP Support): ENABLED OR MODULE (if you don't compile this as a module, you'll have to set "UseInternalAGPGART" to "no" in your XF86Config file)
This option enables AGP support in the kernel, which is usually a good thing to have
Device drivers -> Character Devices -> (pick the correct AGP chipset option from the list, depending on your motherboard): ENABLED OR MODULE
NB: compiling this option as a module is only possible in 2.6 kernels.
NB: AMD64 users: you must also select the AMD Opteron/Athlon64 on-
CPU GART support option in addition to those described above.
Device drivers -> Character Devices -> Direct Rendering Manager (XFree86 4.1.0 and higher DRI support): DISABLED |
